    Small Drainage pipes are all blocked

    What chemicals or solvent could I use to unblock it?

    I know this sounds mental would carwash de-icer stuff unblock or just stop it from blocking further?

    Have a look in the supermarket. Mr muscle does a drain cleaners that expands into foam. That may do the trick.

    It depends what is blocking the pipes
    have you tried a kettle of boiling water

    Negative pipes 20m's longer it needs something that will disolve ice and not dilute

    Depends on what may be blocking it,

    Ice or the usual stuff that blocks pipes?

    if its hair, you will need to take the ubend out unblock by hand or if an object is stuck in it,

    if its a build up of waste food, dependent on what it is may dissolve away,

    commonly blockages, bleach,mr muscle, etc should sort it.




    EDIT

    seen the mention of ice, best thing you can do is leave the hot water tap on, or keep pouring hot water down it,

    liquid de-icer may work you may need quite a bit tho.

    boiling water :?

    A hair dryer run along the pipe will thaw it out.

    Good shout trying to the above already but the pipes on the exterior of the house and its an old house so the wall is on the wind side of the house pretty sure its been frozen over night and as we have used cold water all day until using the shower its had time to freeze the existing water and back all the way up to the ground floor pipes/shower. which is now full so adding to much water inst working well.

    Added deicer and anti freeze screen wash.

    Good luck with it, try not to add any more water, hot or cold, because that will only freeze as well, until you get it sorted.

    If the pipe has frozen over a long distance I suspect the deicer etc won't work. Heating is the best suggestion but if a long length of pipe is frozen by the time you've thawed one end the other may be frozen again. You could try starting from the end nearest where it comes out the house and heat until that section is melting then lag it somehow (old sheets rags etc) and gradually work your way down....paint stripper/heat gun would work better than hear dryer (if you're careful)
